We've tried for about two hours now. He can join his own server, but I can't seem to join. I've tried re-installing both Tekkit and Minecraft; TWICE. He've done it aswell. We both have Hamachi up to the neweste update. I've tried to ping his IP, but I just get 'request denied' or something similar. What the HECK is wrong? We both have the neweste update of Tekkit.
The reason you cannot connect to your friends is because his server is portforwarded, if you use the hamachi IP while his server is online, it wont show up because the hamachi IP isnt put in the server properties, his forwarded IP is, try joining his server with his online IP instead of his Hamachi IP
